DKDP
DKDP, or potassium dideuterium phosphate, is a nonlinear optical crystal. Its chemical formula is KD2PO4. It is a type of phosphate crystal that is a deuterated analog of potassium dihydrogen phosphate (KDP). The substitution of deuterium for hydrogen in the crystal lattice significantly alters its properties. Specifically, DKDP exhibits a higher nonlinear optical coefficient and a lower half-wave voltage compared to KDP. These characteristics make it advantageous for applications requiring efficient frequency doubling or other nonlinear optical processes.
DKDP crystals are commonly used in electro-optic modulators, Q-switches for lasers, and frequency conversion devices. The
